This is prepared by the action of a mixture of Nitric and Sulphuric Acids upon Glycerine. The process requires the greatest care and caution, since Nitroglycerine is a very explosive compound, and any sudden jerk may cause a fatal accident.

As it may now be obtained pure from some of our operative chemists, as a solution in absolute alcohol in the proportion of 1 in 10, the preparation of it need not be attempted by those less accustomed to its manipulation.

Preparation. - Solution in absolute alcohol, 1 in 10.
